The non-linear sigma model (NLSM) is one of the most important effective field theories, both from the theoretical point of view as well
as phenomenologically, whose applications range from
quantum field theory to statistical mechanics and string theory [1]}.
One of the main applications of the NLSM is the description of the low-energy dynamics of pions [2]},
which is performed considering as internal symmetry the \(SU(2)\)  Lie group, that is, the two flavors case.
